virt-viewer/src/virt-viewer-window.c
Christophe Fergeau 20eb200ca5 Exit virt-viewer when trying to close any window 
Currently, in multi-screen scenarios, when closing one remote-viewer
window, the corresponding screen gets disabled in the guest OS.
This can be confusing as this behaves very differently from
File/Quit. This commit will exit the whole application when the user
tries to close one of virt-viewer window.
